"Pollution is a serious danger to the Earth."

Translation: La pollution est un grave danger pour la Terre.

[MandyB11]

Why not "un danger sérieux"? Or "un sérieux danger"? (I'm sure I've usually seen sérieux come second but could be wrong.

[aahahn]

"un danger sérieux" was accepted for me.

[Phlo20]

Not for me. Hmm.

[AjaxJohns]

Why pour la terre and not à la terre?

[uinni]

Because French expresses that complement as "for the earth"

[philverschueten]

Can you put danger grave. It isnt a BANG ADJECTIVE which come before

[OldMansChild]

"...danger grave..." worked for me.
